The STEM ESP32 Coding Box V2.0  is a programming learning toolbox based on Arduino, specially designed for early learners (children over 6 years old). It integrates some of the most basic electronic components and sensors, such as LEDs, buttons, motors, light, sound, infrared and a temperature sensor. Besides, multitudes of interesting projects can be carried out via the Coding Box, including LED flashing, intrusion alarms, smart fans as well as temperature testers.
